Phosphorus was the first chemical element discovered, by scientist Hennig Brand in 1669. then, in 1817, Johann Dobereiner carried out concrete analyses on the atomic weight of calcium, barium and strontium. Also, Dobereiner postulated that in nature there were always triates of elements, and in which it is located in the center, it has characteristics and properties similar to the other two.

Copper (before 9000 BC) According to official history, the origin of the discovery of chemical elements was presented nearly 9000 years before Christ, in the Middle East, more accurately in Anatolia. The Scientific Community says copper was the first to be used by humans. At first, they got it raw as native metal; then extracted from the result of the smelting of the minerals that constitute it.

Gold (6000 to 5500 BC): his background is recorded in Egypt and archaeologists believe it was the first metal used by man. The ancient Egyptians had exquisite jewellery and the proof was found in Queen Zer’s tomb.

Lead (7000 to 3800): Old Egyptians are again listed with the use of metals. It is considered that nine millennia ago, the man began to melt lead. The test was found in the Temple of Osiris in 3800 BC, where they found a strange lead statue.

Silver (about 5000 to 4000 BC) After discovering gold and copper metals, humans in Central Asia discover silver.

Iron (from 5000 to 4000 BC) was discovered in parallel with silver, but today evidence has been found that it has come much earlier being used by humanity. One of these findings was an elaborate account of the metal extracted from a meteorite in ancient Egypt. Likewise, it is estimated that three thousand years before Christ the casting of this metal was implemented. Since then, iron is used for the manufacture of weapons and tools and marks an entire era, called the Iron Age.

Carbon (3750 BC) was only recognized as an element until 1777 A.D., by the scientist Lavoisier. It has been recorded that the primary uses given to charcoal was to reduce copper, tin and zinc, in the process of making bronze carried out by the ancient Sumerios and Egyptians.

Tin (3500 to 2000 BC) by this time, two millennia BC is believed to have made the first blend between brass and bronze.
Sulphur (2000 BC), but archaeological evidence has been captured that in ancient China and India, two millennia before our era was widely used. Like Carbon, it was recognized as an element until 1777 A.D., by the scientist Lavoisier.

Mercury (2000 to 1500 BC) Mercury has been found in Egyptian pantheons estimated 1500 BC and also used by indostani and Chinese.

Zinc (1000 BC) of the mims way that Sulfur, was only recognized as a chemical element until the 800th year of our era, by Rasaratna Samuccaya. But almost a thousand years later he became famous again thanks to Paracelso in 1526 and later by Sigismund Marggraf. But its most remote origins date back to 1000 BC, in India.

Arsenic: (2500 to 1250 BC) as usual at the time, scholars of religion were also engaged in the study of Science and metals, such as the case of St. Albert the Great, the first individual known as the one who isolated the elment in the year 1250.
Antimony: 3000 B.C. famous for Basil Valentín, until 1450 of our era. First known to Egypt and the Middle East three millennia before our era.

Bismuto: 1753 A.D. established as such by Claude Francois Geoffroy.

Phosphorus: year 1669 of our era, made from urine. His manager is H. Brand.

Cobalt: year 1730.

Platinum: 1735 A.D.

Nickel: 1751, also known as nickellin at the time.

Magnesium: 1808 A.D. until that time, it was supposedly discovered that the alba magnesia was not the same lime. H. Davy managed to isolate it electrochemically, based on magnesia.

Hydrogen: year 1766, differentiated from other gases by the laudable scientist H. Cavendish, but Paracelso had already worked it. But his name was given to him by Lavoisier.

Oxygen: year 1771 by W. Scheele.

Nitrogen: Rutherford, 1772.
